Chrysanthemum plant named &#39;DLFLOTU3&#39;

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘DLFLOTU3’, characterized by its upright plant habit; vigorous growth habit; dark green-colored leaves; uniform flowering habit; and excellent postproduction longevity.

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘DLFLOTU3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium, typically grown as a cut flower Chrysanthemum and hereinafter referred to by the name ‘DLFLOTU3’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new cut flower Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination in October, 2012 of a proprietary selection of Chrysanthemum x morifolium identified as code number DB 43373 as the female, or seed, parent with a proprietary selection of Chrysanthemum x morifolium identified as code number DB 43727 as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in April, 2014.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings since April, 2014 has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DLFLOTU3’. These characteristics in combination distinguish ‘DLFLOTU3’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright plant habit; vigorous growth habit.     -   2. Dark green-colored leaves.     -   3. Uniform flowering habit.     -   4. Strong upright flowering stems typically grown as a         single-stem (disbudded) cut flower.     -   5. Large decorative-type inflorescences with light red         purple-colored ray florets.     -   6. Relatively resistant to Fusarium oxysporum f.sp. chysanthemi.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet (FIG. 1 of 2) comprises a side perspective view of a typical flowering stem of ‘DLFLOTU3’ grown as a disbud-type cut flower.

The photograph on the second sheen (FIG. 2 of 2) is a close-up view of lower (top of the photographic sheet) and upper (bottom of the photographic sheet) surfaces of typical inflorescences (left) and leaves (right).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in ground beds in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial cut Chrysanthemum production. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 18° C. to 22° C., night temperatures ranged from 20° C. to 25° C. and light levels averaged 8 klux. Plants were grown as single-stem disbud-type plants and were ten weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.

-   Botanical classification: Chrysanthemum X morifolium ‘DLFLOTU3’. -   Parentage:     -   -   Female, or seed, parent.—Proprietary selection of             Chrysanthemum x morifolium identified as code number DB             43373, not patented.         -   Male, or pollen, parent.—Proprietary selection of             Chrysanthemum x morifolium identified as code number DB             43727, not patented. -   Propagation:     -   -   Type.—Terminal vegetative cuttings.         -   Time to initiate roots, summer.—About six days at             temperatures about 24° C.         -   Time to initiate roots, winter.—About eight days at             temperatures about 22° C.         -   Time to produce a rooted young plant, summer.—About twelve             days at temperatures about 24° C.         -   Time to produce a rooted young plant, winter.—About two             weeks at temperatures about 22° C.         -   Root description.—Fine, fibrous; typically creamy white in             color, actual color of the roots is dependent on substrate             composition, water quality, fertilizers, substrate             temperature and physiological age of roots.         -   Rooting habit.—Freely branching, medium density. -   Plant description:     -   -   Plant and growth habit.—Herbaceous decorative-type cut             flower that is typically grown as a single stem disbud-type;             upright plant habit; vigorous growth habit and moderate to             rapid growth rate. -   Pathogen & pest resistance: Plants of the new Chrysanthemum have     been observed to be relatively resistant to Fusarium oxysporum f.sp.     chrysanthemi. To date, plants of the new Chrysanthemum have not been     observed to be resistant to pests and other pathogens common to     plants grown under commercial conditions. -   Temperature tolerance: Plants of the new Chrysanthemum have been     observed to tolerate temperatures ranging from about −12° C. to     35° C. and to be suitable for USDA Hardiness Zones 8 to 10.
